Answer:
The brown paper weighs 80 ounces.
Step-by-step explanation:
Since the brown paper takes up 1/4 of the 20 pounds of paper in the box, there are pounds of brown paper.
We know that 1 pound = 16 ounces, so 5 pounds of brown paper weighs 5 * 16 = 80 ounces.
The brown paper weighs 80 ounces.

Below in bold.
Step-by-step explanation:
y = 2x²-4
First find x in terms of y:
2x² = y - 4
x² = (y - 4)/2
x = √ [(y - 4)/2]
Now replace x by the inverse f-1(x) and y by x:
f-1(x) = √ [(x - 4)/2] (Note: it's the positive square root only)
